Simple rules can help fishery managers cope with ecological complexity [Phys]

par Frédéric Magné - publié le

To successfully manage fisheries, factors in the environment that affect fish—like food sources, predators and habitat—should be considered as part of a holistic management plan.That approach is gaining traction in fisheries management, but there has been no broad-scale evaluation of whether considering these ecosystem factors makes any economic sense for the commercial fishing industry. In these often profitable and competitive markets, that question has lacked the evidence to rule one way or another.
A team of ecologists and economists has addressed that question in the first study to test whether real-life ecological interactions produce economic benefits for the fishing industry. The results were published online last week in the Proceedings of the National Academy of Sciences.
